To all whom it may concern: 7

Be it known that I, J AMES NAYLOR, of Providence, in the county ofProvidence and State of Rhode Island, have invented a new and ImprovedSlat-Adjuster for VVindow- Blinds, of which the following is a full,clear, and exact description.

The object of my invention is to provide a practical and convenientdevice for adjusting the slats to window-blinds to hold them at anydesired angle when the blinds are closed; and the invention consists ofthe construction, arrangement, and combination of parts, all ashereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in allthe figures.

Figure l is an inside sectional view of the lower part of a windowcasing and blinds, showing my invention applied to the blinds, theright-hand screw or worm shaft being removed to show the lifting deviceand the slot in the casing to receive it. Fig. 2 is a sectionalelevation taken on the line w w of Fig.1, and Fig. 3 is a plan view ofone of the lifting devices removed.

A represents the window-sill, and B the inside portion of the sill or acasing closed by the top piece or cover, 0. In the casing B and cover Gare journaled the two screws or worm-shafts D, one for each blind E. Theworms D are each provided at their upper ends, above the cover 0, with aknob, c, by which they may be conveniently turned to the 5 right orleft, and 011 each worm is placed a lifting device, F, so that byturning the worms these may be raised or lowered for raising or loweringthe slat-rods G, to which the slats g of the blinds are attached. Theslat-rods G are kept in position in line with the lifters F by thesleeves H, secured to the window-blind. The lifters in this instance areeach formed with an upright portion, f, top plate, f, and lowerhorizontal arm, f which is flattened 5 and formed with the threadedaperture f through which the screw or worm shaft passes, and the liftersin this instance are held in position for direct vertical movement bybeing placed in narrow cavities J, formed in the 50 window-sill. Thelower ends of the shaft D are journaled upon stepblocks K, as shownclearly in the drawings.

Having thus fully described my invention, I claim as new and desire tosecure by Letters 5 5 Patent- The screws D, fitted in the window-sill,in combination with the lifters F, arranged to be moved vertically bythe screws into engage ment with the slat-rods G of the blinds, sub 60stantiall y as and for the purposes set forth.
